Many gun lovers who want a larger caliber AR-15 platform rifle choose the AR-10. There are a lot of manufactures to choose from for their components. The Faxon Firearms .308 BCG is a step above the competition for your next upgrade.

What Makes the Faxon Firearms AR10 BCG Unique?

Material speaking the .308 BCG is an 8620 carrier and a 9310 steel bolt which is an upgrade from the traditional Mil-Spec. Faxon also uses an S7 tool seal on the extractor which means that it has better shock resistance and durability. A super finish is performed on their BCGs through a post-machining mechanical chemical finishing process, resulting in a super low-surface finish that is abrasion-resistant and is smoother than Mil-Spec. This AR10 BCG does not feel gritty like regular Mil-Spec BCG’s and there are no machining lines.

Faxon Firearms Superior Standards

This .308 BCG is nitrate treated to provide outstanding hardness, decreased resistance, and outstanding corrosion resistance. Lastly, all Faxon Firearms bolt carrier groups are magnetic particle inspected to ensure they are absolutely defect-free and heat-treated to exacting military standards. This means that Faxon Firearms BCGs deliver a notably smoother bolt cycling operation and reliability than many of their competitors.

What This Mean for You

Faxon Firearm standards translate into a smoother, stronger, and more reliable bolt carrier group for your AR10. Faxon Firearms BCGs are full-auto-rated and are perfect for fully automatic fire and multi-stage trigger systems. All Faxon products are protected by their lifetime guarantee ensuring a lifetime of service for you and your firearm.
